Need some advice please. My Nitrate level in my tank has risen from 10mg to 50mg in a space of 2 months. I added a br-110 pellet reactor about 2 weeks ago. The level hasn't gone any higher than 50mg, but it hasn't gone down either. I'm using a 2100Lph pump. It moves the pellets, should i be using a stronger pump? What else can i do to bring the nitrate level down?

Based on personal experience though I would say definitely make use of an airstone with them; don't think that the flow coming from your overflow (for instance) is enough flow...@dallasg helped me when I setup/had problems with my cubes with some great advice...
